Tympanic Muscles and Control of Auditory Input during Arousal

A. Hugelin 1, S. Dumont 1, and N. Paillas 1

1 Hôpital Henri Rousselle, Paris, France

A reticular stimulation producing a powerful arousal reaction decreases the potential in the cochlear nucleus evoked by a click. This reduction results from the contraction of the middle ear muscles, which lessens the pressure transmitted to the cochlea, and is not due to a direct neural inhibitory effect at the level of the first synapse of the auditory pathway.
